reproduction

When my virtual table has user selection and Table.removeAll() is called the table receives a SetData event with Event.index == -1.

Repro:
1. Run the attached code, ensure that it says it runs under GTK3.
2. Click on an item in the table (might take several tries).
3. Watch messages in stderr as removeAll() is called to update the table.

SWT 4.527, GTK 3.10.8, Ubuntu 14.04

Bug 320838 is a possible duplicate but it's very old so i made a new one.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
